Unless there's a reason for wanting to access the home machine, I'd just buy an external (USB) hard drive and plug it in. I got one off Ebay that did the job perfectly. Some time later, the "home" HD in the laptop died and I transplanted the one out of the USB caddy and installed that.
That's easy to do, and also gives you a handy little device for backups, moving files about, and all sorts.
